It’s only practical for 10% of users, how dare they waste resources on developing this. If you are part of this 10% minority, tough luck, we have majoritarian rule here. [/sarcasm]
Oh, and for any use with a permanently attached drive (eg, Time Machine), the floor is often enough not a problem (you might have ’bought’ a SD card slot you don’t use but strangely most people seem to prefer to rather have more ports than less even if they don’t need all of them).
not many people want to leave a hard drive on the floor, to the OP's point. You like to use that phrase how dare you don't you? and more ports? you mean one more port. Any real hub typically has five or more. Not two. how dare you! lol
